STEEL FORGED SHOE FOR TIE-BANDS.

Specification of Letters Patent.

Application filed March 3, 1908.

Patented April 13, 1909.

Serial No. 419,068.

T c all whom it may concern:

Be it known that I, HENRY DRUM, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Steel Forged Shoes for Tie-Bands, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to coupling-shoes for the ends of tie-bands and the process of making the same.

The object of the invention is the provision of a shoe device of this nature which is capable of being manufactured from forged steel or wrought iron and whereby the product is rendered more durable and stronger than where the shoes are made by casting or analogous processes.

llith these ends in view, the invention consists in the adaptation and configuration of a coupling-shoe, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal vertical section of a coupling-shoe constructed in accordance with my invention; and Fig. 2 is a plan view of the same. Fig. 3 is a plan view of a blank from which the shoe is made. Fig. at is a representation of the blank with the wings at the rear folded for 'ardly upon the body thereof.

Referring to Figs. 1 and 2, the numeral 5 designates the central web or base of the shoe which is made concave upon its underside (3 to a curvature, longitudinally, of approximately that of the pipe or other objectupon which it is to be employed. The shoe is provided with flanges T which extend upwardly from the sides of the base and are of substantially triangular shape in longitudinal elevation. At the rear of each of these flanges they are severally made of a double thickness, as at 8, by folding the edges of the flanges inwardly upon themselves and in such a manner that the surfaces at the bends 9 and at the shoulders 10 thus produced will be inclined from a medial vertical plane. The shoulders 10 afford a support for the underside of the head 11 provided upon one end of a tie-band 12, and the bends 9 serve to support the nut 13 which is screwed upon I the shoe is tapered at the heel and too, as at 15 and 16, respectively, so as to allow the band being in close relation with the pipe to within a short distance from the extremities of the shoe. To make the shoe more stable and present a larger bearing surface to the pipe, the base in proximity of the shoe is made, as at 17, somewhat wider than the remainder.

The manner of making the aforedescribed shoe may be explained as follows: The sheet steel is first sheared or stamped out to pro vide a trapezoidal blank, as illustrated in Fig. 3, and is symmetrical with respect to a longitudinal axis a ir. At one end is a reentrant angle whose sides 18 terminate in a recess 19 having curved sides 20 and 21. The sides of this angle and of the recess are also arranged symmetrically to the aforesaid axis. The next step in the manufacture is to upset or fold, as by pressure or through blows delivered by a hammer, the portions along diagonal lines y and over upon the body of the blank, causing the device to then appear as in Fig. l. The article is then pressed by suitable punch and die in a machine so as to fold the side portions 7 upwardly about the lines to form the aforesaid flanges 7 and press the various parts to produce the configuration illustrated in Figs. 1 and 2.

Having described my invention, what I claim,

1. As a new article of manufacture, a forged coupling-shoe, comprised. of a central web from which extend upwardly two side flanges, said web being formed of greater width at one end than the other, and said flanges being folded back upon themselves so as to afford oppositely disposed supports for the head and nut of a pipe band.

2. As a new article of manufacture, a forged coupling-shoe, formed from a blank which is treated so as to provide the same with a central web, two flanges extending upwardly from the web and having portions of said flanges doubled so as to respectively provide obliquely arranged bea ing surfaces for the head and nut of a pipe-band.

A coupling shoe composed of a base, side flanges extending upwardly from said base, said flanges at their rear ends being folded inwardly upon themselves, the donbled over portions forming one support and the free vertical side edges of the doubled l inner faces of the bodies of said side flanges,

over ends conjointly forming shoulders to engage the head and nut of a pipe band.

l. A coupling shoe composed of a base, and side flanges, one end of each of said side flanges being doubled over and forming supports at their doubled over portion and at their free side edges and a band seat between their inner faces, said band seat being composed of continuations of the inner ends of said side flanges.

5. A coupling shoe composed of a base and side flanges, said side flanges being doubled over at one end to form a U-shaped seat for the tie band and opposite supports for its head and nut.

6. A coupling shoe composed of a base, side flanges extending upwardly from said base, the rear ends of said flanges being bent over and extending inwardly to engage the said flanges at their inner ends being bent to seat on said base.

7. A coupling shoe composed of a base, side flanges extending upwardly from said base, the rear ends of said flanges being provided with extensions which are bent over and extend inwardly, said flanges at their points of bending forming surfaces for engagement with the nut on the tie band, and at their free ends being disposed at points intermediate the ends of the base to provide shoulders to engage the head of the tie band. In testimony whereof I affix my signature in presence of two witnesses.

HENRY DRUM.
